HENRY M. PAINE, OF NEWARK, NEW JERSEY.

IMPROVEMENT 5N STENClL-PEN3.

Specification forming part of Letters Patent No. iihiifliZti, dated July3, 1877 application filed March 13,1877.

To all whom it may concern:

Be it known that i, HENRY Mormon PAINE, of the city of Newark, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in Electro-Magnetic Stencil-Pens; and 1 do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain improvements in stencilingtools, thefirst of which is the mechanical construction and arrange ment of anelectromagnetic motor operating a style; secondly, the method or172061108 0 emndi of reciprocating the said style.

Referring to the drawings, Figure 1 represents a plan view, partly insection, of the open frame-work surrounding the magnetic motor. Fig. 2is an elevation of the same. Fig. 3 is a side view of the magnetic bar.Fig. 4 is a plan of said bar. Fig. 5 represents the style-bar; and Fig.6an elevation, partly in section, showing the combination, of the Figs.1, 2, 3, 4, and 5.

Similar letters of reference represent like parts in all the figures.

The frame referred to in Figs. 1 and 2 is fashioned of soft iron, andthe armatures a a a a, which are a continuation of the frame bars 0 0 c0, may be of any even number.

The magnetic bar I) b is fitted to a spindle, e, and on the lower end ofthe spindle is projected a toe,f. The center of the spindle is drilledout, as shown in dotted lines at h. The magnetic bar 12 b and spindle 6,thus constructed, are arranged in position within the aforesaidsoft-iron frame, under such conditions that the spindle 0 will movefreely in the shank i of the frame, and the poles at of the magnetic barI) b will rotate closely between the armatures a a. a a, which form anintegral part of the said frame.

Fig. 5 is a style-bar, n, which receives and holds the markingtool at oby means of a binding-collar, P. The upper end n of the stylebar n isfitted loosely into the drilled end h of the spindle e, and a wave-cam,7', is permanently secured to the bar a.

When the above-described individual parts have been placed in position,as shown at Fig. 6, it will be seen that the toe f engages the cam runder conditions which compel the style-bar a, when prevented fromrotating by the stops, to reciprocate under and by the rotary movementof the magnetic bar Z) I).

The compensating spiral spring t, acting on a stopcollar, 1 keeps thetoe f and cam r in contact, while the binding center-screw 12 securesthe whole combination in position.

The number of reciprocates of the style'bar n, as regards therevolutions of the magnetbar, will be as the number of waves on the faceof the cam T, which may be two or more. Having described the individualparts of my invention, 1 would here state that its novelty consists inthe construction of a stenciling style, n, operated by means ofhorizontally-revolving magnets, in combination with an open armature,forming an integral part of the frame-work surrounding and supportingsaid magnetic bars, for the purpose of operating the style a withwave-cam r, compensating-spring t, and stop 8; therefore,

What I claim as my improvement is A hand stencil pen or style consistingof magnetic bars b i), revolving in an open armature-frame, Figs. 1 and2, in combination with a cam, r, having two or more waves cast orotherwise secured upon the upper end of the bar 92., within thecircumference thereof, and toe f, stop 8, spring 2, all constructed,arranged, and operating, for stenciling purposes, upon paper or otherthin substances, in the manner substantially as above set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

HENRY MONROE PAINE.
